Power, in general, is defined as the rate at which energy is transferred or converted or the rate of doing work. Thus, power can be calculated using the formula P = W / t. On the other hand, power is a scalar quantity and is basically the amount of energy consumed per unit time which… Continue reading Unit of Power

What is Viscosity? Viscosity is defined as the quantity that represents a fluid’s resistance to flow. To put it in more simple terms, viscosity is the friction between the molecules of the fluid. We usually relate to the viscosity of a liquid by measuring the “thickness”. For example, we can state that honey is “thicker” (meaning… Continue reading Unit of Viscosity

The pressure is usually defined as the amount of force that is applied to a certain area. The pressure is a physical quantity and mostly expressed as formula p = F/A where F and A are force per area perpendicular to the surface. While we have already discussed everything about pressure in our earlier article,… Continue reading Unit Of Pressure

What is Lenz’s Law? Lenz’s law states that The induced electromotive force with different polarities induces a current whose magnetic field opposes the change in magnetic flux through the loop in order to ensure that original flux is maintained through the loop when current flows in it. Named after Emil Lenz, Lenz’s law depends on… Continue reading Lenz`s Law

Faraday’s law of electromagnetic induction, also known as Faraday’s law, is the basic law of electromagnetism which helps us to predict how a magnetic field would interact with an electric circuit to produce an electromotive force (EMF). This phenomenon is known as electromagnetic induction. Michael Faraday proposed the laws of electromagnetic induction in the year… Continue reading Faraday`s Laws of Electromagnetic Induction

In electromagnetism, Ampère’s circuital law relates the integrated magnetic field around a closed loop to the electric current passing through the loop. In this article, let us learn in detail about Ampere’s Law. What is Ampere’s Law? According to Ampere’s law, magnetic fields are related to the electric current produced in them. The law specifies… Continue reading Ampere`s Law

We know light is the form of energy which can undergo various phenomenons like refraction, reflection, diffraction, and interference. In this session, let us know more about laws of reflection (first law of reflection and second law of reflection), types of reflection, examples, differences, and total internal reflection. What is Law of Reflection? Definition: The… Continue reading Laws Of Reflection

Kirchhoff’s circuit laws lie at the heart of circuit analysis. With the help of these laws and the equation for individual components (resistor, capacitor and inductor), we have the basic tool to start analyzing circuits. In this article, we will discuss Kirchhoff’s current and voltage law and how to employ them in circuit analysis. History… Continue reading Kirchhoff’s Law

Doppler effect or Doppler shift is a phenomenon that is observed whenever the source of waves is moving with respect to an observer. For example, an ambulance crossing you with its siren blaring is a common physical demonstration of the Doppler Effect. In this article, let us understand the intricacies of the Doppler effect in… Continue reading Doppler Effect

Archimedes principle deals with the forces applied to an object by fluids surrounding it. This applied force reduces the net weight of the object submerged in a fluid. In this article, let us familiarize ourselves with Archimedes principle. What is Archimedes Principle? Archimedes’ principle states that: “The upward buoyant force that is exerted on a… Continue reading Archimedes Principle
